slapos/promise/plugin/check_cpri_lock: Don't check whatever device blindly
Currently this promise is implemented by grepping whole rf_info output for "HW" and "SW" strings. But this won't work ok in the presence of multiple CPRI devices. Imagine, for example if one device has CPRI lock, while the other does not: PCIe CPRI /dev/sdr2@1: Hardware ID: 0x4b12 DNA: [0x0048248a334a7054] Serial: '' FPGA revision: 2023-06-23 10:05:24 FPGA vccint: 0.98 V FPGA vccaux: 1.76 V FPGA vccbram: 0.98 V FPGA temperature: 71.9 °C Clock tune: 0.0 ppm NUMA: 0 CPRI_option: '5' (x8) lock=no <-- NOTE DMA0: TX fifo: 66.67us Usage=16/32768 (0%) DMA0: RX fifo: 66.67us Usage=16/32768 (0%) DMA0 Underflows: 0 DMA0 Overflows: 0 PCIe CPRI /dev/sdr3@1: Hardware ID: 0x4b12 DNA: [0x0048248a334a7054] Serial: '' FPGA revision: 2023-06-23 10:05:24 FPGA vccint: 0.98 V FPGA vccaux: 1.77 V FPGA vccbram: 0.98 V FPGA temperature: 71.7 °C Clock tune: 0.0 ppm NUMA: 0 CPRI_option: '5' (x8) lock=HW+SW rx/tx=46.606us <-- NOTE Port #0: T14=46.606us DMA0: TX fifo: 66.67us Usage=16/32768 (0%) DMA0: RX fifo: 66.67us Usage=16/32768 (0%) DMA0 Underflows: 0 DMA0 Overflows: 0 the old code would still report "CPRI locked all ok" and also globally without indicating which CPRI channel is locked. -> Fix it by adjusting check_cpri_lock to parse rf_info text more precisely, detect devices there and to understand which device has CPRI lock and which does not.
